Methods and apparatus for allocating a data region (termed “sticky region allocation”) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame so that a user terminal can receive/send data bursts for multiple OFDM/OFDMA frames, rather than inserting a MAP information element (MAP IE) for each user terminal in every frame, are provided. In this manner, the size of the control overhead, such as the downlink (DL) and uplink (UL) MAP messages, may be reduced. The reduced control overhead may increase the frame resources available for data traffic and thus, may boost the overall efficiency and performance of wireless systems using OFDM/OFDMA.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method comprising: receiving a first signal based on a first orthogonal frequency division multiple access (OFDMA) frame having a first MAP information element (IE) comprising a frame number of a starting OFDMA frame; locating a data region related to a data burst in the starting OFDMA frame according to the first MAP IE; receiving a second signal based on a second OFDMA frame, wherein the second signal is received later than a signal based on the starting OFDMA frame; locating the data region related to a different data burst in the second OFDMA frame without using a second MAP IE; and decoding the second OFDMA frame without using a MAP IE different from the first MAP IE.
A wireless communication method involves a device receiving a first signal from a base station in an OFDMA frame. This frame includes a MAP IE that specifies the frame number where a data region starts, allowing the device to find a data burst within that starting frame. Later, the device receives a second signal from another OFDMA frame and locates a different data burst in a data region *without* needing a second MAP IE. The second OFDMA frame can then be decoded without using any MAP information element other than the initial one.
2. The method of claim 1 , wherein the data region is a downlink (DL) data region and the first MAP IE is a DL-MAP IE.
The wireless communication method from the previous description focuses on downlink data. Specifically, the data region is a downlink (DL) data region, and the initial MAP IE used to find the starting frame is a DL-MAP IE (Downlink Map Information Element). This means the base station is allocating a specific region for downlink data transmission that the device can keep using without requiring explicit instruction in every subsequent frame.
3. The method of claim 1 , wherein the data region is an uplink (UL) data region and the first MAP IE is a UL-MAP IE.
The wireless communication method from the first description uses an uplink data region for transmission from a user device back to the base station. The initial MAP IE is a UL-MAP IE (Uplink Map Information Element). This indicates the base station is allocating a dedicated region for uplink data transmissions, reducing overhead.
4. The method of claim 3 , wherein an uplink map (UL-MAP) for the second OFDMA frame has a starting slot offset appearing before all MAP IEs in the UL-MAP such that the data region may be located correctly.
Building upon the uplink data transmission method in the previous description, the second OFDMA frame's uplink map (UL-MAP) includes a starting slot offset positioned before all other MAP IEs. This offset enables the receiver to correctly locate the assigned uplink data region, ensuring proper synchronization and data extraction in the absence of a dedicated MAP IE for that frame.
5. The method of claim 1 , wherein the first MAP IE contains a message having region information for determining a fixed position for the data region within the starting and the second OFDMA frames.
In the wireless communication method of the first description, the first MAP IE carries a message. This message includes "region information" that defines a fixed location for a reserved data region within both the starting OFDMA frame and subsequent OFDMA frames. By fixing the position, the receiver can locate data without requiring a MAP IE in every frame.
6. The method of claim 5 , wherein the region information comprises at least one of a symbol offset, a subchannel offset, a number of symbols, a number of subchannels, a boosting level, a permutation type, and a repetition coding type.
Expanding on the previous description, the "region information" from the initial MAP IE may contain one or more of these details to define the data region: a symbol offset, a subchannel offset, the number of symbols, the number of subchannels, a boosting level, a permutation type, and a repetition coding type. This allows for a flexible yet fixed allocation of resources.
7. The method of claim 5 , wherein the region information comprises at least one of a slot offset, a slot duration, and a repetition coding type.
Expanding on the description of region information within the MAP IE, the location of the data region can be specified by a slot offset, a slot duration, and a repetition coding type. This provides an alternate approach for defining the data region's location and encoding specifics for subsequent frames without per-frame MAP IEs.
8. The method of claim 5 , wherein the message comprises the starting frame number and an allocation interval related to the data region.
Extending the description of the MAP IE message, the message contains a starting frame number *and* an allocation interval. The starting frame number specifies the first frame where the data region is valid, and the allocation interval defines how often that data region will be available in subsequent frames.
9. The method of claim 5 , wherein the message comprises at least one of an allocation identifier, an ending frame number, a Downlink Interval Usage Code (DIUC) or an Uplink Interval Usage Code (UIUC), and acknowledgment (ACK) region information.
Further details within the MAP IE message can include: an allocation identifier, an ending frame number, a Downlink Interval Usage Code (DIUC) or an Uplink Interval Usage Code (UIUC) specifying the purpose of the data region, and acknowledgment (ACK) region information indicating how to acknowledge received data.
10. The method of claim 1 , wherein the first MAP IE is from the starting OFDMA frame.
The first MAP IE, the information element that defines the "sticky region," originates from the *starting* OFDMA frame, the initial frame from which the data region allocation is defined. This ensures the receiving device gets the initial allocation information from the correct frame.
11. The method of claim 1 , further comprising locating the data region in one or more subsequent signals based on subsequent OFDMA frames until a MAP IE that specifies termination of allocation of the data region is received.
After finding the initial data region using the first MAP IE, the data region can be located in one or more subsequent signals based on subsequent OFDMA frames. This process continues until a MAP IE is received that *explicitly terminates* the allocation of that data region, freeing up those resources.
12. A method comprising: receiving a first signal based on a first orthogonal frequency division multiple access (OFDMA) frame having a first MAP information element (IE) comprising a frame number of a starting OFDMA frame; locating a data region related to a data burst in the starting OFDMA frame according to the first MPA IE; receiving a second signal based on a second OFDMA frame, wherein the second signal is received later than a signal based on the starting OFDMA frame; and locating the data region related to a different data burst in the second OFDMA frame without using a second MAP IE, wherein the first MAP IE contains a message having region information for determining a fixed position for the data region within the starting and the second OFDMA frames, wherein locating the data region in the starting OFDMA frame comprises using the starting frame number and the region information and locating the data region in the second OFDMA frame comprises using the allocation interval and the region information in the message of the first MAP IE such that the second frame is received a number of OFDMA frames after the starting frame according to the allocation interval.
A wireless communication method involves receiving a first signal from a base station in an OFDMA frame that includes a MAP IE. This MAP IE contains a frame number of a starting OFDMA frame.

The original MAP IE includes a message with region information used to find the data region in both frames. The second frame is received a number of OFDMA frames after the starting frame as indicated by the allocation interval found in the first MAP IE's message.
